Draw a circle R on the trademark to declare that it is a legally registered trademark and is protected by the trademark law.

But sometimes because the style when applying for a trademark is different from that when using it, it is ok not to circle R.

R is definitely a registered trademark. If it is not added, it cannot be said that it is not a registered trademark. If the unregistered trademark plus R is illegal, you can report it to the industrial and commercial department.

In addition, China's protection of well-known trademarks is very strong, so whether R is used or not does not mean anything. After all, people's influence is there.
